DTB123EK is a PNP digital transistor with built-in bias resistors for inverter, interface, and driver applications, packaged in an SOT-346 (SC-59) surface-mount case. It has a collector-emitter voltage rating of -50 V and a maximum collector current of -500 mA. The integrated input resistors are both 2.2 kΩ, enabling simple biasing without external components. Power dissipation is rated at 200 mW, with a maximum junction temperature of 150 ℃. The device meets RoHS standards and is designed for surface-mount assembly using reflow soldering.
These are the standard products of "digital transistors" which ROHM invented and marketed first in the world.
